AUXILIARY PRESSURE-REGULATOR FOR GAS-BURNERS.

Specification of Letters Patent.

Patented April 7, 1908.

Application filed August 26, 1907 Serial No. 390,163.

To all whom it may concern:

Be it known that I, HENRY FARNOFF, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Auxiliary Pressure-Regulators for Gas-Burners, of which the following is a specification.

My invention relates to auxiliary regulators for inverted incandescent gasburners.

In inverted gas-burners now in use, the

an auxiliary-regulator which can be moved to its open'position when the pressure .of the gas is weak, and can be closed fully or to any extent desired according to the increase in pressure.

It also has for its object, the production of a regulator of this type which can be applied to any form of burnenand which is arranged to beconveniently operated to move the same into any desired position.

Still further objects are, to provide a simple and inexpensive regulator which can be easily dismantled and the parts thereof disassembled, and to equip one part thereof \gith means for suspending the mantle there- The invention consists in the construction, arrangementand combination of parts to be hereinafter described and particularly pointed out in the subj oined claims.

In the drawings,-Figure 1 is a central vertical section through an inverted incandescent burner embodying my invention in preferred form. Fig. 2 is an enlarged horizontal section taken on line 22, Fig. 1. Fig. 3 is a vertical section taken on line 33, Fig. 4 is a detached perspective view of the cli whereby the supply-pi e is securedto t e crown of the burner. ig. 5 is a detached perspective view of the upper member of the auxiliary regulator-casing. Fig. 6 is a detached perspective view of the rota-,

table screen located within the regulatorcasing. Fig. 7 is a detached perspective view of the lower member of the regulatorcasing. Fig. 8 is a sectional elevation of a modified form of burner showing the rotatable form of auxiliary regulator illustrated in Fig. 1., applied thereto. cal section of a still further modified form of burner showing a modification of the auxiliary-regulator.

Referring to the drawings'in detail, like letters of reference refer to like parts in the sexgeral figures. 1 h

' re resents the su i e aving a downweii'dly curved terr fi fn al B and a regulator C by means of which the supply of gas to the burner is governed. The supply-pipe is secured to a crown D by means of a cllp which embraces said pipe and has ears 6 that are riveted to said crown. The latter is rovided with clamping-screws F adapte to impinge against the upper end of a globe G and securely hold said globe to the crown.

H designates the auxiliary pressure-regulator, the casing of which comprises-an upper member h and a lower member 72.; said upper member being externally threaded at its upper end for engagement with internal threa s in the downwardly curved terminal of the sup 1y-pipe, and said lower member having a tu e extension h provided with projections I separated by grooves J and havin notches K in their upper ends. Each of t e mem bers of the auxiliary regulator has a substantially semi-spherical portion L and the upper member has an enlarged cylindrical portion M which fits over the lower member and is secured thereto by means of screws m.

N designates a circular screen which may be termed the regulator proper, and O is a spindle having a depressed and flattened intermediate portion 0 to which said circular screen is secured; said depression being formed to position the screen in line with the axis of the spindle. The two members of the regulator casing are provided with coinciding notches 0 arranged at diametrically opposite points in which the cylindrical ends of the spindle O are held; one end-of said spindle having a head 0 which bears against the outer surface of the enlarged cylindrical portion of the upper member, and at its other end an operating handle P is secured; said handle having a socket p which bears Fig. 9 is a central vertiagainst the enlarged cylindrical end of the upper member at a point diametrically o posite the head 0 In this manner t I e regulator is retained in proper positlon withln the casing so that it will rotate freely when manipulating the operating-handle w thout binding or coming in contact with the Walls of the casing.

R designates a mantle holder which has inwardly directed ears 1" that are set in the notches K in the upper ends of the projections I on the lower member of the auxiliary regulator casing; said holder having a mantle S secured thereto in any approved manner.

In the modification shown in Fig. 8, the supply-pipe enters the burner-tube at the top and said tube has the upper portion of the auxiliary-regulator casing formed integrally therewith; said tube and casing asillustrated in this figure, may be constructed of porcelain. The operating handle designated T is curved outward at its upper end to pass through an opening t in t e crown of the holder;

In the modification shown in Fig. 9, the supply-pi e is illustrated in the form of a goose-nee: and has a regulator U at 1ts lower end. The upper end of said supplypipe is threaded into a cylindrical casing V aving a reduced externally threaded lower end '0 onto which is threaded a tube vvhaving projections '0 onto which a mantle-holder '0 into the path of the gas entering t 1s held; sai holder having a mantle '0 secured thereto. The upper end of said cylindrical casing has a cap V provided with an axial threaded opening in which a screw w is threaded and which extends into said casing and has a circular screen w secured to its lower end in any ap roved manner. Secured to the upper en of said screw is a disk X provided at its edge with notches and adapted to be engaged by hand for revolving the screw. The screen has a range of movement from a point above the opening in the supply-pipe to a point beneath the same so that it may be moved wholly or artially l ie cylindrical casing from said pipe, or entirely clear of said supply of gas, as may be desired.

It is clearly apparent from the foregoing that when the pressure of as is weak the auxiliary-valve may be manipulated so that the gas does not pass throu h the screen, and that said screen may be rought into' the path of the gas to the extent desired, dependmg on the increase of ressure of the gas, so as to supply the mant e with the gas under pro er pressure for best results.

aving thus described my invention, what I claim is,-

1. In an incandescent gas-burner, the combination with a gas supp y-pipe having a gasregulator and a mantle, of an auxiliary-regulator between said first-mentioned regulator said su ply-pipe and mantle having a screen movab e to compel the sup ly of gas to pass therethrough or to permit t e gas to ass directly to the mantle without passing t rough said screen.

4. In an inverted incandescent gas-burner, the combination with a sup ly-pi e and a mantle, of an auxiliary-regulator having a screen movable to allow part of the supply of gas to pass therethrough or movable out of the pat of the gas.
